Mucormycosis of temporal bone is extremely rare. They are usually associated with host immunodeficiency, are difficult to diagnose, and many cases are fatal. We performed a literature review and found only 10 reported cases of temporal bone mucormycosis. We present a case of temporal bone mucormycosis involving the temporomandibular joint and infratemporal fossa in a 53-year-old woman with diabetes mellitus who presented with unbearable otalgia. Computed tomography and magnetic resonance imaging demonstrate inhomogeneous density mass in the parapharyngeal and retropharyngeal space accompanied with lytic bone destruction on the temporomandibular joint. After undergoing a biopsy of the left infratemporal fossa, the patient’s pathology exhibited fungal hyphae consistent with mucormycosis. To our knowledge, this is the first report of temporal bone mucormycosis with extensive involvement of temporomandibular joint and its adjacent structures, which exhibited no otologic or rhinologic signs. A definitive diagnosis is made by biopsy.

AbstractBackground:Gorham–Stout disease of the skull is a very rare entity. It presents with gradual bone resorption, and proliferation of lymphoid and vascular channels within the bony matrix. This is often a diagnosis of exclusion confirmed with serial imaging and based on radiological evidence.Case report:A case of Gorham–Stout disease of the temporal bone involving the temporomandibular joint, and presenting with sensorineural hearing loss and recurrent temporomandibular joint dislocation, is reported. The findings are presented and the literature on this condition is reviewed.Conclusion:ENT and maxillofacial surgeons should be aware of this extremely rare cause of temporomandibular joint dislocation and ear symptoms. Imaging comprising computed tomography and magnetic resonance imaging is crucial to achieving a diagnosis, which may only become evident after repeated imaging follow up. Symptomatic treatment is advised, with the option of anti-osteoclastic medication and radiotherapy indicated for advanced cases. Surgery is only recommended for complications including involvement of neurovascular structures.

AbstractBACKGROUND:Subtotal temporal bone resection (STBR) has been used for half a century to remove temporal bone malignancies. However, there are few reports on the detailed anatomy involved in the resection.OBJECTIVE:To describe the microsurgical anatomy of STBR combined en bloc with the resection of the parotid gland and temporomandibular joint (TMJ).METHODS:Cadaveric specimens were dissected in a stepwise manner using 3× to 40× magnification.RESULTS:STBR can be combined with the total parotidectomy and the resection of the TMJ if the tumor extends into the parotid gland, TMJ, or facial nerve. In this study, we describe the step-by-step microsurgical anatomy of STBR en bloc with the parotid gland and TMJ. The surgical technique described combines 3 approaches: the high cervical, subtemporal-infratemporal fossa, and retromastoid-paracondylar approaches. Combining these 3 approaches aided in efficiently completing this modified approach.CONCLUSION:STBR is a complicated and technically challenging procedure. This study highlights the importance of understanding the surgical anatomy of STBR and will serve as a catalyst for improvement of the surgical technique for temporal bone resection.

AbstractWhen it comes to examining the brachial plexus, ultrasound (US) and magnetic resonance imaging (MRI) are complementary investigations. US is well placed for screening most extraforaminal pathologies, whereas MRI is more sensitive and accurate for specific clinical indications. For example, MRI is probably the preferred technique for assessment of trauma because it enables a thorough evaluation of both the intraspinal and extraspinal elements, although US can depict extraforaminal neural injury with a high level of accuracy. Conversely, US is probably the preferred technique for examination of neurologic amyotrophy because a more extensive involvement beyond the brachial plexus is the norm, although MRI is more sensitive than US for evaluating muscle denervation associated with this entity. With this synergy in mind, this review highlights the tips for examining the brachial plexus with US and MRI.

To identify and localize an intraorbital wooden foreign body is often a challenging radiological issue; delayed diagnosis can lead to serious adverse complications. Preliminary radiographic interpretations are often integrated with computed tomography and magnetic resonance, which play a crucial role in reaching the correct definitive diagnosis. We report on a 40 years old male complaining of pain in the right orbit referred to our hospital for evaluation of eyeball pain and double vision with an unclear clinical history. Computed tomography and magnetic resonance scans supposed the presence of an abscess caused by a foreign intraorbital body, confirmed by surgical findings.
